I applied for a vacancy and attached a cover letter specific to the job vacancy [Vacancy 1]. The status of the vacancy [Vacancy 1] is "shortlisting".
However, I would like to apply for other jobs in UN/UNOPS [Vacancy 2]. Can i delete the cover letter and attach a new one to apply for a new vacancy [Vacancy 2]? Or will this affect my application on Vacancy 1?

Would really appreciate any insight/clarification on this query.

Thanks in advance.

Do not delete any relevant attachment, instead create a new and give it a specific name i.e: Your Name Type Job Title/Ref No

While doing that your each application supplementary supporting document will be saved in your profile. You can delete from the list of attachments once you know for sure, you are not the one...
